Quantum Science News

Taking a major stride forward in a research field that was awarded the 2016 Nobel Prize in Physics, an international research team has discovered that topological materials—substances that have strange electronic behaviors—are actually very common, and include usual elements such as gold and arsenic.

The universe, in the early times, was an energetic blend of powerfully interacting particles. The first particles to split free from this thick soup were neutrinos, the lightest and most feebly interacting particles of the Standard Model of particle physics.

Quantum computers will process considerably more information simultaneously compared to present-day computers. But the building blocks that hold this information—quantum bits, or “qubits”—are extremely sensitive to their environment to function sufficiently well at the moment to create a practical quantum computer.

A team of Australian engineers and scientists has designed the local infrastructure for the world’s largest radio telescope – the Square Kilometre Array (SKA) – taking the billion-dollar global project one step closer to reality.

In the worldwide pursuit for creating practical computing and communications devices based on quantum principles, one prospectively useful component has been unachievable: a source of light containing individual particles that is ideally predictable, constant, and with steady characteristics.

A potential link between correlated neutrons and protons in the nucleus, together with a 35-year-old mystery, has been unraveled by a meticulous re-analysis of data obtained from the Department of Energy’s Thomas Jefferson National Accelerator Facility.

A flat crystal of 150 beryllium ions (electrically charged atoms) has been “flash-frozen” by physicists from the National Institute of Standards and Technology (NIST), paving the way for new opportunities to simulate magnetism at the quantum scale and to sense signals emitted by mysterious dark matter.

Electro-optic modulators (EOMs) are an easy to use and efficient tool to externally modify the phase, frequency, polarization or amplitude of a free-space laser. In contrast to acousto-optic modulators the spatial mode of the laser beam remains unaltered.
